Standing 201-metres tall with a 19-metre wide capacitive 'top hat', the 3WV mast in western Victoria stands out in the vast flat landscape that stretches below it.

Celebrating 75th years of service, the occasion of World Radio Day seemed a worthy time to pay tribute to this impressive technological structure.

"It really meant a lot to us. It must've been a big undertaking in 1936 to build it because cranes and things that are about today weren't even heard of," says long time Horsham resident James Heard.

And while the locals are proud of the trusty Dooen mast, its power reaches far wider than just this wide brown land.

In fact 594 AM has even been heard as far as Canada, Japan and South Africa.

The staggering reach is aided by the distinctive 'top hat' and the low frequency of the AM band. While obviously a success, the antenna was the first of its kind in Australia and acted as a prototype for other services.

"It's the first solid-state 50-kilowatt broadcast transmitter installed for the ABC and it was the test bed for the installations across the rest of the country," says Tim Hughes, Transmission Coordinator for ABC Victoria.

So whether you're tuning in from snowy Canada or just down the road, thanks be to the 3WV transmitter.
